I use all shearwell, tags. Stick reader, mobile app and nlmd website. I can't fault it. Bluetooth weigh head works really well. Its very cheap at only £30 per year for the software. It can't do everything a full on program will do but very very nearly does everything i need. 2 things missing are service details and management number for cattle. I can put up with that but i nearly wish it cost a bit more and they had more cash to develop it further.
